Description
Oppfinnelsen vedrører en framgangsmåte til rensing av reaksjonsprodukter som oppstår ved flammeforbrenning av brennstoffer, som inneholder forurensninger som for eksempel svovel-, klor- og fluorforbindelser, ved tilførsel av tilsetningsmidler, som binder forurensningene, i forbrenningsrommet. The invention relates to a method for cleaning reaction products that arise from the flame combustion of fuels, which contain pollutants such as sulphur, chlorine and fluorine compounds, by supplying additives, which bind the pollutants, in the combustion chamber.
Det er tidligere kjent framgangsmåter for gjennomfø-ring av tørr rensing av reaksjonsprodukter fra forbrenning av brennstoffer som er forurenset med eksempelvis svovel, There are previously known procedures for carrying out dry cleaning of reaction products from the combustion of fuels that are contaminated with, for example, sulphur,
klor og fluor. Tilsetningsstoffene, som skal binde forurensningene, blir innført i forbrenningsrommet på forskjellige måter. chlorine and fluorine. The additives, which are supposed to bind the pollutants, are introduced into the combustion chamber in different ways.
Ved en første kjent framgangsmåte går en fram slik at tilsetningsmidlene blir innsprøytet ovenfor flammeområdet i forbrenningsrommet ved hjelp av luftstråler. Ulempen med denne kjente framgangsmåten består i at innføringsmåten for tilsetningsmidlene i forbrenningsrommet ikke sikrer at tilsetningsmidlene binder forurensningene. Grunnen til dette er at luftstrålenes forholdsvis ubetydelige blandingsenergi ikke strekker til for å oppnå en tilfredsstillende blandingsgrad for reaksjonsdeltakerne. Blandingen av reaksjonsdeltakerne skjer dessuten for det meste i temperaturområder som er forenlige med optimale reaksjonsbetingelser. En annen ulempe består i at den oppholdstid som står til rådighet til avslut-ning av reaksjonen er utilstrekkelig, fordi innsprøytingen av tilsetningsmidlene vanligvis skjer i reaksjonstrege om-råder. In a first known method, one proceeds so that the additives are injected above the flame area in the combustion chamber by means of air jets. The disadvantage of this known method is that the method of introducing the additives into the combustion chamber does not ensure that the additives bind the contaminants. The reason for this is that the relatively insignificant mixing energy of the air jets is not sufficient to achieve a satisfactory degree of mixing for the reaction participants. The mixing of the reaction participants also mostly takes place in temperature ranges that are compatible with optimal reaction conditions. Another disadvantage is that the residence time available for completion of the reaction is insufficient, because the injection of the additives usually takes place in slow reaction areas.
Ved en annen kjent framgangsmåte går en fram slik at tilsetningsmidlene blir blandet med brennstoffet rett før sistnevnte innføres i brenne.ren. Denne framgangsmåten ut-merker seg i ugunstig retning ved at tilsetningsmidlene blir utsatt for flammens totale temperaturspektrum, og de må gjen- noraløpe temperaturområder som fører til at de blir uvirksom-me. Dette gjelder særlig ved brennstoffer med høy varmeverdi, hvilket nødvendigvis fører til flammer med høye temperaturer. In another known procedure, one proceeds so that the additives are mixed with the fuel just before the latter is introduced into the incinerator. This method has a disadvantage in that the additives are exposed to the entire temperature spectrum of the flame, and they must again run through temperature ranges which cause them to become inactive. This applies in particular to fuels with a high calorific value, which necessarily leads to flames with high temperatures.
Oppfinnelsen har følgelig tatt sikte på å videreutvik-le en framgangsmåte av det slag, som er angitt innlednings-vis, på en slik måte at det sikres at tilsetningsmidlene, The invention has consequently aimed to further develop a method of the kind, which is indicated in the introduction, in such a way that it is ensured that the additives,
som skal binde forurensningene, ved tilførselen blir ført slik sammen med reaksjonsproduktene fra forbrenningen på ett sted og i én form i forbrenningsrommet at det oppnås de for bindingen nødvendige forutsetninger med hensyn til temperatur og blandingsgrad. which is to bind the pollutants, during supply is brought together with the reaction products from the combustion in one place and in one form in the combustion chamber so that the conditions necessary for the binding are achieved with regard to temperature and degree of mixing.
I samsvar med oppfinnelsen er dette oppnådd ved at tilsetningsmidlene blir tilført brennerflammen ved hjelp av en gassformet og/eller flytende bæremiddelstrøm under dannelse av et slør som omgir brennerflammen. In accordance with the invention, this is achieved by the additives being supplied to the burner flame by means of a gaseous and/or liquid carrier stream while forming a veil which surrounds the burner flame.
Som bæremiddel kan det benyttes forskjellige stoffer. Ifølge et første utførelseseksempel på framgangsmåten ifølge oppfinnelsen kan det som bæremiddel benyttes forbrenningsluft i form av en delluftstrøm. Various substances can be used as a carrier. According to a first embodiment of the method according to the invention, combustion air in the form of a partial air flow can be used as a carrier.
Ifølge oppfinnelsen er det også mulig som bæremiddelAccording to the invention, it is also possible as a carrier
å anvende en blanding av forbrenningsluft og røkgass.to use a mixture of combustion air and flue gas.
En annen mulighet er å benytte ren røkgass som bæremiddel for tilsetningene. Another possibility is to use clean flue gas as a carrier for the additives.
Ifølge framgangsmåten kan det som bæremiddel også anvendes en vanlig suspensjon. According to the procedure, a normal suspension can also be used as carrier.
Som tilsetningsmidler kan det benyttes metalloksyder eller hydroksyder i samsvar med patentkrav 6, eller tilset-ninger som angitt i patentkrav 7. As additives, metal oxides or hydroxides can be used in accordance with patent claim 6, or additives as stated in patent claim 7.
Ved at stedet og. formen for tilførselen av tilsetningsmidlene i området for flammen under anvendelse av en gassformet eller flytende bæremiddelstrøm er klart fastlagt på forhånd, blir det oppnådd reaksjonen mellom tilsetningene og forurensningene, fra brenngassene til enhver tid vil foregå der hvor de optimale reaksjonsbetingelser foreligger. By that the place and. the form of the supply of the additives in the area of the flame using a gaseous or liquid carrier flow is clearly determined in advance, if the reaction between the additives and the pollutants is achieved, from the combustion gases at all times will take place where the optimal reaction conditions exist.
Foruten fastsettelsen av stedet og formen for tilførselen av. tilsetningsmidlene kan valget av bæremiddel påvirke reaksjons-prosessen i retning av ytterligere optimalisering. Dette gjelder for eksempel når brennstoffer med høye flammetempera-. turer kan påvirke tilsetningenes virkning i negativ retning. Dessuten kan blandingsforløpet for reaksjonsdeltakerne bli styrt i retning av en reaksjonsoptimalisering gjennom valget av impulsstrømmen for tilsetnings-bæremidlet. Besides the determination of the place and form of the supply of. additives, the choice of carrier can influence the reaction process in the direction of further optimization. This applies, for example, when fuels with high flame temperatures. trips can affect the effects of the additives in a negative direction. In addition, the mixing process for the reaction participants can be controlled in the direction of reaction optimization through the selection of the impulse current for the additive carrier.
Framgangsmåten ifølge oppfinnelsen beskrives i det følgende under henvisning til tegningen som viser en kull-støvbrenner, som framgangsmåten eksempelvis kan anvendes i forbindelse med. The method according to the invention is described in the following with reference to the drawing showing a coal dust burner, with which the method can for example be used.
Med den skjematisk viste brenner, som består av kjer-neluftrør 2, brennstoff- og kullstøv-bæreluftdel 1 og kappe-luftdel 3, blir det frambrakt en primærforbrenningssone 6. Lufttallet for nevnte sone ligger mellom 0,8 oh 1,1 ganger det støkiometriske. With the schematically shown burner, which consists of core air tube 2, fuel and coal dust carrier air part 1 and jacket air part 3, a primary combustion zone 6 is produced. The air number for said zone is between 0.8 and 1.1 times the stoichiometric .
Brenneren er utformet slik at det. ved bestemte for-holdsregler (strømningsbevegelsen for kappeluften, konisk utvidet brennermunning, sluttet kjerneluftstrømning) er frambrakt en sone med intensiv motstrømning 5 i det indre av flammen og fra et område med allerede tiltagende forbrenning. Dette resulterer i hurtig oppvarming og tenning av brennstoff -luftblandingen. Opphetningen og antennelsen av blandingen kan påvirkes ved innstilling av kjerneluftmengden. The burner is designed so that by certain precautions (the flow movement of the jacket air, conically widened burner mouth, closed core air flow) a zone of intensive counterflow 5 is produced in the interior of the flame and from an area of already increasing combustion. This results in rapid heating and ignition of the fuel-air mixture. The heating and ignition of the mixture can be affected by setting the core air quantity.
Den resterende forbrenningsluft blir i form av en delluftstrøm 4, sammen med tilsetningsmidler, som skal binde de gassformete stoffer som dannes, ved forbrenningen, blåst inn via dysen ved omkretsen på en slik måte at det oppstår et delluftstrøm-tilsetningsmiddel-slør omkring flammen. På grunn av nevnte slør utvikler det seg utenfor primærflammen en sekundærflamme eller etterreaksjonssone 7 som via del-luftstrømmen forsynes med oksygen og skadestoffbindende til-setninger. Delluftstrømmen 4 blir derfor anordnet i en del-sirkel som tilsvarer minst den dobbelte kappeluftrørdiamet-eren. Dette sikrer at delluftstrømmen 4 med tilsetningsmidlene først etter en strekning på ca. 1 til 2 ganger kappe-luftrørdiameteren når den egentlige flamme nedstrøms av bren-nermunningen og utenfor de temperaturområder som har svek-kende innvirkning på tilsetningsmidlenes aktivitet. Tilfør-selen av tilsetningsmidlene til delluftstrømmen 4 skjer over en ledning 8, nemlig i området for reguleringsorganet for delluftmengden, ettersom det på dette sted er sikret en god sammenblanding på grunn av strømhvirvlene. The remaining combustion air is blown in via the nozzle at the perimeter in the form of a partial air flow 4, together with additives, which are to bind the gaseous substances that are formed during the combustion, in such a way that a partial air flow-additive veil occurs around the flame. Due to the aforementioned veil, a secondary flame or post-reaction zone 7 develops outside the primary flame, which is supplied with oxygen and pollutant-binding additives via the partial air flow. The partial air flow 4 is therefore arranged in a partial circle which corresponds to at least the double casing air pipe diameter. This ensures that the partial air flow 4 with the additives only after a stretch of approx. 1 to 2 times the jacket air tube diameter reaches the actual flame downstream of the burner mouth and outside the temperature ranges that have a weakening effect on the activity of the additives. The supply of the additives to the partial air flow 4 takes place via a line 8, namely in the area of the regulating body for the partial air quantity, as good mixing is ensured at this location due to the current vortices.
På de avsnitt av flammens omkretsflate, som ikke ligger nær delluftstrømningen 9, blir det ved impulsutbytting suget inn røkgass fra forbrenningsrommet. Dette fører til en nedsettelse av flammetemperaturen, hvilket bidrar til en gun-stig innvirkning på reaksjonsforløpet mellom tilsetning og gassformete skadestoffer. On those sections of the flame's peripheral surface, which are not close to the partial air flow 9, flue gas is sucked in from the combustion chamber by impulse exchange. This leads to a reduction in the flame temperature, which contributes to a favorable effect on the course of the reaction between the additive and gaseous pollutants.
